International Cores

Magnetec Cool Blue cores are for use as common-mode chokes. According to the company, the cores suppress asymmetrical EMI currents generated by the parasitic currents of motors and their cables.

Magnetec Cool Blue cores are for use as common-mode chokes. According to the company, the cores suppress asymmetrical EMI currents generated by the parasitic currents of motors and their cables. Made from iron-based nanocrystalline, the product provides a range of permeability, 25,000-90,000 at 10 KHz, and a saturation flux density of 1,200 mT. In addition, they are available in a range of M-type sizes, including round and oblong shapes. The smallest core for high-power motor applications has an outside diameter of 63 mm and inside diameter of 50 mm. The largest core has a 500-mm outside diameter and 450-mm inside diameter. Standard thickness is 30 mm.
